phenylalanine--tRNA ligase subunit alpha

phenylalanine--tRNA ligase subunit alpha is the catalytic subunit of the enzyme complex that catalyzes the attachment of phenylalanine to tRNA(Phe)

phenylalanine--tRNA ligase subunit alpha

Catalyzes a two-step reaction, first charging a phenylalanine molecule by linking its carboxyl group to the alpha-phosphate of ATP, followed by transfer of the aminoacyl-adenylate to its tRNA; forms a heterotetramer of alpha(2)beta(2); binds two magnesium ions per tetramer. Most phenylalanyl-tRNA synthetases are heterodimeric, with 2 alpha (pheS) and 2 beta (pheT) subunits. This HMM describes the alpha subunit, which shows some similarity to class II aminoacyl-tRNA ligases.
